I was interrupted by a knock at the door. It was the mail lady with got a registered letter from the IRS. When I opened the letter, it turned out it was an official communication from that agency announcing that a refund I applied for when I did back taxes was denied. The refund would have been for $13.00 and arrived today, on Friday the 13th. There were two copies of the multi-page paperwork. Generating this denial had to have cost hundreds of dollars.
